IMPROVEMENT IN LIQUID MEASURING DEVICES.

i Specification forming part of Letters Patent No. 215,300, dated May13, 1879; application filed December 6, 1878.

To all whom it may concern:

Be it known that I, WARDELL B. SHERMAN, of Utica, in the countyof Oneidaand State of New York, have invented certain new-and useful Improvementsin SelfiMeasuring Devices; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it pertains to make and use it,reference being had to'the acco1npauying drawings, which form part ofthis specification.

My invention consists of the parts and combination of parts hereinafterdescribed and claimed.

Figure 1 represents a perspective view of my improved measuring device.Fig. 2 represents a cross-vertical section. Fig. 3 represents a topview, and Fig. at represents the positionof the force pnmp.

In Fig. 1, A represents a tank or reservoir, which may hold any numberof gallons of fluid; B, the measuring-vessel, which contains theplunger; 0, the dial, which is divided into eight sections, each sectionrepresenting one pint; I), the crank, which sits into the notches aroundthe dial, and-also turns the cog-wheel E, which rolls up and down thenotched rack F of the plunger. G is a conductor, with a funnel-shapedend, which can be raised or lowered to reach into any size can or jugstanding 011 the drip-pan, avoiding the use of funnels. H is aforcepump, to force the fluid from the tank or reservoir into the vesselB. I is a case, with sliding doors, 850.; and J is a sealed glass tubeextending down the side of the tank or reservoir, to show the quantityof fluid within.

In Fig. 2, K-is the plunger within the vessel B. M is the orificethrough which the pump forces the fluid from the tank A into the vesselB. N is the outlet to the conductor G and the can or jug, and 0 showsthe connection of the sealed glass tube to the reservoir A.

In Fig. 3, P is a drip-pan, into which may be set the can or jug underthe conductor G.

In Fig. 4., Q Q is the force-pump, showing its shape and position inrelation to the vessel and reservoir.

To operate this device, draw the plunger K up to the top of the vessel Bby turning the crank 1). Then with the forcepump till the vessel B withfluid until it runs out through the conductor G. Place the index at thetop notch of the dial. Then, if you wish to draw from the vessel onepint, turn the index to the right one notch on the dial; if a quart, twonotches; if a gallon, make one complete revolution of the index, and sorepeat for any number of gallons, according to the size of the vessel.

The vessel may be made of any suitable material, and of any size orshape.

The plunger may be'made of any suitable material, and of any form, andof a size to displace a given quantity of fluid in the vessel.

Having thus described my invention, what I claim, and wish to secure byLetters Patent,

1. In a measuring device, the combination, with an upright rack, thelower extremity of which is provided with a plunger, and a single piniondirectly gearing therewith, of a crank secured to the arbor of saidpinion and a vertical registeringdisk provided with aforwardly-proiectingrim having notches, in which latter the free end ofsaid crank is adapted to have lateral engagement, substantially as setforth.

2. In a measuring device, the combination, with the upright reservoir,measuring-chamber, and intermediate pump-connection, of a plungervertically working in the measuringchamber, a pinion havingrack-engagement with said plunger-rod, a crank formed on the arbor ofsaid pinion and a registering-disk having notches cut in theright-angular rim formed thereon, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this3d day of December, 1878.

WARDELL B. SHERMAN.
